Specifying event triggering conditions

Objective

To specify when you want an event to generate and whether you want it sent to the Tivoli Enterprise Console server or Tivoli Business Systems Manager.

Background information

Only events can notify that there is a problem in the resource state, trigger an action and, if enabled, send a notification to the Tivoli Enterprise Console server or to the Tivoli Business Systems Manager.

Before you begin

Select one or more properties from the monitored properties and specify the conditions that must be satisfied to generate an event. For more information about events, see Events and indications.

When you finish

After creating a trigger condition, the datasource displays the triggers below it. You can remove a trigger by right-clicking on it. Double-clicking opens the trigger for editing. Right-clicking on the selected datasource allows that datasource to be deleted along with all triggers created with it.

You have the option to select properties to log, as described in Selecting the properties to log. You can also add another CIM, monitoring collection, or custom script datasource. Then, specify the resource model cycle time as described in Entering a cycle time.

Procedure

  1. Double-click a property to open the Event Triggering Condition window.
  2. Select one of the following logical operators from the drop-down list:

    Numeric property options:

    >
    Records the value of the selected property, compares it to the value you specify in the text box, and triggers an event if the current value is greater than the specified value.
    <
    Records the value of the selected property, compares it to the value you specify in the text box, and triggers an event if the current value is less than the specified value.
    =
    Records the value of the selected property, compares it to the value you specify in the text box, and triggers an event if the current value is equal to the specified value.
    <>
    Records the value of the selected property, compares it to the value you specify in the text box, and triggers if the current value is not equal to the specified value.
    >=
    Records the value of the selected property, compares it to the value you specify in the text box and triggers an event if the current value is larger than or equal to the specified value.
    <=
    Records the value of the selected property, compares it to the value you specify in the text box and triggers an event if the current value is smaller than or equal to the specified value.
    Increases at least by
    Checks the current value of the selected property against the previous value and triggers an event if the current value is greater than the previous one by a value equal to or greater than the value you specify in the text box.
    % increases at least by
    Checks the current value of the selected property as a percentage of the previous value and triggers an event if current value is greater than the previous one by a value equal to or greater than the value you specify in the text box.
    Decreases at least by
    Checks the current value of the selected property against the previous value and triggers an event if the current value is smaller than the previous one by a value equal to or greater than the value you specify in the text box.
    % decreases at least by
    Checks the current value of the selected property as a percentage of the previous value and triggers an event if current value is smaller than the previous one by a value equal to or greater than the value you specify in the text box.
    Changes by
    Compares the previous and current values of the selected property and triggers an event if between these two values there is a difference equal to the value you specify in the text box.
    Changes at least by
    Compares the previous and current values of the selected property and triggers an event if between these two values there is a difference equal to or greater than the value you specify in the text box.
    Is out of the range
    Compares the current value of the selected property against the defined range limits, and triggers an event if the current value falls outside the specified range.

    String property options:

    Is equal to
    Records the value of the selected property, compares it to the value you specify in the text box, and triggers an event if the current value is equal to the specified value.
    Is not equal to
    Records the value of the selected property, compares it to the value you specify in the text box, and triggers an event if the current value is different from the specified value.
    Contains
    Records the value of the selected property, compares it to the value you specify in the text box, and triggers an event if the current value contains the specified value.
  3. Enter a string or numeric value in the text box next to the drop-down list.

    Additional Information: Specifying the logical operator and value builds the logical expression.

  4. Enter the number of occurrences of the specified condition that must be detected before the resource model generates an event.
    Note:
    The number of occurrences must be greater than zero.
  5. Enter the number of holes allowed before the resource model generates an event.
    Note:
    The number of holes must be greater than, or equal to, zero.
  6. Select the Event severity from the drop-down list.
  7. (Optional) Select the first check box if you want an event to generate when the conditions that had previously caused an event get resolved.
  8. (Optional) Select the remaining two check boxes if you want to send this event to the Tivoli Enterprise Console server or Tivoli Business Systems Manager.
  9. Click OK to return to Specify the Event Triggering Conditions window.
  10. (Optional) Repeat this procedure for each event you want to generate.
  11. Click Next to proceed with the wizard.
